IMPROVEMENT IN GAS-REGULATORS.

Specification forming part of Lett rs Patent No. 152,083, dated June16,1574; application filed February 25, 1874.

To all whom it may concern:

Be it known that I, J ULES ANSELME Cnn'rn, of Gorbeil, near Paris,France, printer, have invented a GasRegulator, applicable also for otherfluids; and I do hereby declare that the following is a full, clear, andexact description of the same, reference being had to the annexed sheetof drawings, making a part of the same.

The object of my invention is an improve ment in regulators for gas andother fluids, in which a ball or sphere is confined in a tube orchamber, through which the fluid passes, and rises or falls, as thepressure is greater or less, thus obstructing the delivery. My regulatorconsists of a tube, box, or chamber fitted on the gas-burner, thewater-pipe, &c., and formed at its upper part with a central channel ofdefinite section, on the inner sur face of which grooves 0r recesses areformed, which increase the sectional surface thereof. The number andsection of these grooves or recesses is so calculated that, supposingthe central channel to be obstructed, there will pass through thegrooves (which constitute so many distinct passages leading to theburner proper, or to the water-outlet) only a desiredquantity of gas orwater; or, in other words, the regular delivery. Thus, for a burner toconsume ten thousand cubic feet for a definite time, the channel in theregulator may have three grooves or additional recesses. For a burner toconsume fourteen thousand cubic feet, the channel may then have fourgrooves, or three only, but of larger section than those of theten-thousand-cubic-feet burner. The lower part of the central channel isconical, and the body of the regulator is so set that, when the deliveryof gas or water is shut up, a small sphere rests on a seat at a certaindis tance beneath the cylindrical portion of the channel or passage. Theseat consists of two or three pins, which retain the sphere above thecenter of the inlet-pipe without closing it completely, leaving aroundthe same free passages, while the space between said seat and thegrooved channel forms a case or chamber, into which the sphere can rise.

The whole, as above described, will constitute either a tube or a box,which, being provided with a screw-thread at either end, will be fittedwith the utmost facility, either on a burner or a water-pipe.

The operation is as follows: The deliverycock being shut, the spherestands resting on its seat. If, now, the cock is opened, and thepressure is superior to two -fifths of an inch, the sphere then willrise; and, getting near to the conical part of the central channel, willgive access to the burner of only the quantity of gas passing throughthe grooves in said channel and the annular section existing betweensaid sphere and the channel surface. Should the pressure increase, thenthe sphere will narrowmore and more the annular space, so far as tocompletely annul it, and the gas will then escape only through thegrooves, which are adapted for delivery of a volume of gas sufficientfor the normal consumption of the burner. hen the pressure subsides theinverse effect will be produced, the sphere lowering, and thusincreasing the escape section. \Vhen the pressure gets beneathtwofifths'of an inch, the sphere will drop again to its seat, and thegas will escape through the entire channel and its grooves.

Now, the advantage offered by my regulator, chiefly so far as concernswork-shops, is that it will be no longer requisite to be constantlyoccupied in opening and closing the deliverycock more or less, accordingto the variations of pressure, as said cock is to remain constantly wideopen for the good working of the system, the number of the grooves andtheir sections being calculated for a given delivery or consumptionunder the ordinary normal pressure. ing will be the same when theregulator is applied to a water-pipe.

I have represented, as an example, in the annexed drawings, a regulatorof my system as applied to a gas-burner. I

Figure 1 shows a central vertical section of the burner, the sphereresting 011 its seat. Fig. 2 shows a similar section, the sphere formingan obturation for normal delivery. Fig. 3 shows a horizontal section ofthe burner through the line 1 2, Fi 1; and Fig. 4 shows, on a largerscale, a vertical section of the regulator proper.
